What can be cooked from squid: quick and tasty

The degree and quality of wastewater treatment depend on the structures and methods used. One of the most effective is biological. For this, a special station is being installed at the dacha. It cleans up all waste water. Details and reviews - below.

Station for biological treatment: description, principle of operation

Most often, the issue related to the disposal of polluted water and waste is of concern to residents of the private sector, summer residents, owners country cottages, recreation centers, campings. After all, where, if not far from cities with an established sewerage system, you have to think about what to do and how to filter the drains. This is where biological wastewater treatment plants come to the rescue. Working from the mains, they clean sewage waste and take it to any place equipped for this: a ditch, filtration fields, etc.

Connecting a biological treatment station to the sewerage system of the house

The principle of operation of the station is based on the vital activity of microorganisms that are initially in the wastewater. They have the ability to reproduce in special devices under favorable conditions. For bacteria to work, air is needed, which is specially pumped into the purification system for this. Under its action, microorganisms decompose sewage waste, resulting in the formation of brown flakes - activated sludge. It is considered good fertilizer, so use the station on summer cottage very appropriate.

Advice. It is not necessary to add additional bacteria to the biological treatment plant. Useless here will be special "leavens", which are used to treat cesspools, dry closets. Be aware that the composition of the microorganisms contained in such preparations and in wastewater differ from each other.

Facilities and methods for biological wastewater treatment

By the types of microorganisms that are involved in cleansing Wastewater, there are 2 methods:

1. With the help of aerobic bacteria, which require oxygen to function. With this method of cleaning, biofilters and aeration tanks are used, which are more effective. It is as a result of their use that activated sludge is formed, which is used to fertilize vegetable gardens.
2. With the help of anaerobic microbes that live without oxygen. They start the fermentation process and convert organic waste into methane and carbon dioxide. For this, metatenki are used. The anaerobic method requires less investment, because additionally no aeration occurs (air saturation).

Attention! For the greatest efficiency, experts recommend using installations in which both types of microorganisms are involved.

Methods for purifying polluted waters using aerobic microorganisms are divided according to the type of container where waste waste is oxidized:

• biopond;
• filtering field;
• biofilter.

Station with aeration tank

The use of the first two structures has features:

• seasonality - they work only during the warm season;
• relatively low productivity;
• the need to use large tracts of land.

Biological treatment stages. Station installation

The biostation is a container that is divided into several compartments. In the first of them there is a mechanical purification of water from solid household waste and the accumulation of sediment. It needs to be removed periodically. Further, depending on the design features, the already slightly purified water is poured either into the secondary sedimentation tank (metatenk or anaerobic chamber) or into the biological treatment compartment. In it, the further process takes place with the help of a biofilter or aeration tank.

Attention! The degree of water purification in an aeration tank is better than in a device with a biofilter. In addition, such a station is not required. additional insulation... But the biofilter is more convenient to use, in particular, it is autonomous in terms of electricity.

The station fits into the design of almost any summer cottage, because it can be:

• install underground;
• deepen by half (if groundwater passes close to the surface)
• put on a land plot (relevant for devices that do not work all year round, but only in warm weather).

Station setup diagram

It is better to trust the assembly of the station to professionals, since the cost of an error during installation can be very significant. For example, a properly installed structure is not a source of an unpleasant odor, since it is absolutely hermetically sealed. In addition, due to improper installation, expensive parts gradually fail.

Pros and cons of a biological treatment plant. Owner reviews

Station advantages:

• high environmental friendliness;
• ease of use;
• durability, since there are no metal parts;
• versatility - suitable for any soil;
• compactness;
• high performance;
• the need for maintenance is rare.

Disadvantages of biological treatment devices:

• high price the system itself, as well as expensive service costs;
• restrictions on use - it is not recommended to drain substances containing chlorine;
• the need to constantly use the station, because during long breaks, microorganisms die.

True, the latter drawback loses its relevance if you choose a device, for example, with a self-oxidation system of activated sludge.

Owner reviews indicate that when correct installation and the operation of the station, there are no problems: filters do not clog, the seam on the body does not diverge, parts do not break. In addition, one should take into account such observations of those who managed to test the devices on their site:

It is very important to carry out the installation correctly.

1. Despite the lack of recommendations from manufacturers, it is better to insulate some biological stations.
2. Waste of some vegetables, for example, mushrooms or tomatoes, it is better not to dump into the sewer: they are not recycled.
3. The drains of the bath or shower stall, as well as sinks, should be equipped with special nets that trap hair, otherwise the filters will quickly clog.
4. Draining from the washing and dishwasher need to be equipped separately, as aggressive detergents can destroy microorganisms.

Advice. The highest efficiency - the degree of purification up to 98% - is provided by a three- or four-stage processing system. This indicator is typical only for stations. Simpler devices, with filters, have a rate of 65%. Keep this in mind when deciding to equip a bio-sewage system on the site.

Any developer for improvement country house sooner or later puzzled by the question of how to arrange a local sewer system. Modern technologies will solve this issue in several ways, including a treatment station, a septic tank made of concrete rings, and so on. But for the choice the best option a comprehensive solution is needed.

Wastewater treatment methods

You need to know that there are two ways to treat wastewater: anaerobic and aerobic.

The first method is used in different types septic tanks - ranging from simple overflow septic tanks made of concrete rings and ending with local treatment facilities. The second method of purification is used in autonomous sewage systems - deep biological treatment stations.

The first method is used in various types of septic tanks - from simple overflow septic tanks made of concrete rings to local treatment facilities. The second method of purification is used in autonomous sewage systems - deep biological treatment stations.

Concrete ring septic tank

This type of local treatment plant, working on anaerobic principle, despite its simplicity and cheapness, requires a thoughtful approach. Here are the features this type of septic tank may have.

Chief engineer of the company "Artesium" Dmitry Zadrutsky:

- Although this type of treatment plant on the site is often built independently, a number of features of this type of septic tank should be taken into account:

• Purification in this type of septic tank occurs by overflowing wastewater from the chamber to the chamber. And therefore, they install 3-chamber septic tanks made of concrete rings.
• Pay attention to the diameter of the rings. The volume of the septic tank depends on this. The larger the number of people living, the more you need the volume of the septic tank and the number of chambers.
• If there is a high level on the site groundwater, then in order to avoid the seepage of contaminated water into the soil, better sealing of the septic tank is required.
• For better purification of the effluent, you can use special bacteria, and for additional purification of the effluent, it is recommended to arrange a filtration field.

The disadvantages of this type of septic tank include:

• The complexity of installation and a large amount of earthwork;
• Unlike plastic septic tanks, complete tightness of the joints of the rings is not ensured;
• The need to use special equipment and a crane for the installation of a septic tank.

This septic tank can be discharged toilet paper, personal care products and drain from washing machine, but a dishwasher discharge is no longer desirable. fatty deposits are formed on the walls of the main pipe. It is impossible to use water for irrigation, and it is necessary to periodically call a sewer truck to pump out the septic tank.

Local treatment plant

To understand what processes are taking place in this type of septic tank, the managing partner of the company will help us "Triton Plastic"(Moscow) septic tank manufacturer" TANK» Vladimir Pivovarov:

- NS The principle of operation of septic tanks: waste water from household devices is directed by gravity through pipelines to the first chamber of the septic tank, where it is naturally separated into light - fats, oily substances, organic waste and heavy components. Heavy fractions sink to the bottom and eventually turn into silt, the lungs, together with water, enter the second chamber for anoxic processing by anaerobic bacteria, and then, if there is one, into the third chamber.

And the final purification of wastewater is carried out already in the filtration fields, selected based on the absorbing characteristics of the soil in the area and the depth of groundwater during installation.

Organic sludge accumulated in the receiving chamber of the septic tank as a result of the processing of heavy fractions from wastewater is periodically disposed of by pumping through the hose of a sewage machine.

It should be noted that this type of septic tank requires a mandatory device of filtration fields. Since the water after the septic tank is purified by about 60-70% and requires additional purification for discharge into the ground.

After the additional purification process, the water is purified to almost 99%. However, it is not recommended to use these drains for irrigation or other needs.

Vladimir Pivovarov:

- For seasonal accommodation, pumping is required once every 1-3 years, depending on the number of people living and the intensity of use. This can be assessed by visually opening the manhole cover in the septic tank in front of winter period... At permanent residence pumping out once a year or with the addition of bacteria every 5-8 years.

In the conditions of seasonal residence, it is necessary only once a year to pump out the sediment from the septic tank when it is preserved for the winter period.

And with permanent residence, using the filling of special bacteria for intensive decomposition of the sediment, about once a month, pumping is required much less often, only once every 5-8 years.

The septic tank can be used for any type of soil, including non-filtering and with a high level of groundwater.

To the main advantages of this type treatment facilities relate:

• Long service life - over 50 years;
• Ease of operation and energy independence;
• The possibility of processing in moderate amounts of organic substances that enter the septic tank along with wastewater ( detergents, paper or cigarette butts);
• The strong ribbed surface of the septic tank, and its manufacture of extra strong plastic, increases the resistance to aggressive chemicals and seasonal temperature changes.

Deep biological treatment station

We figure out what advantages the biological treatment plant has and how the effluent is purified.

Company expert "SBM - Group" producing autonomous local sewerage systems "UNILOS"Beskishchenko Maxim .

- The principle of operation of the station of deep biological treatment is based on the method of continuous cultivation of microorganisms, which occurs under the influence of oxygen, or as it is also called the method of aeration. And the purification of effluents occurs due to activated sludge obtained from bacteria and microscopic animals.

Activated sludge is active biomass suspended in water, which carries out the wastewater treatment process in an aeration tank. A large community of microorganisms formed during biological treatment intensively oxidizes organic matter.

Thanks to the organic substances in the wastewater and the excess oxygen entering the installation, these bacteria begin to develop rapidly and then stick together into flakes, after which they release enzymes that mineralize organic pollution. When sludge with flakes enters the outlet clarifier, it quickly settles, separating from the treated water.

The biological treatment station allows the use of treated water for irrigation. And activated sludge formed in the aeration tank is very similar in structure to river sludge and is a valuable fertilizer. So you don't have to call a sewer truck.

Unlike cesspools, a biological treatment station does not accumulate sewage, but ensures their biochemical decomposition into simple, safe compounds - industrial water and stabilized activated sludge, therefore, there is no bad smell. Therefore, a biological treatment station can be installed near the house, at a distance of 2 meters, and the treated water can be immediately discharged to the terrain without using additional soil treatment systems.

We deal with the features of the operation of such a system.

Beskishchenko Maxim:

- Despite the reliability of the system, there are a number of rules that must be followed for the effective operation of the deep cleaning station, namely: it is forbidden to dump construction waste into the sewer, chemical substances, polymer materials, petroleum products and other non-biodegradable compounds. And in the event of a power outage, it is necessary to reduce water consumption, since the receiving chamber of the biological treatment station may overflow and the untreated wastewater may enter the environment. It is also necessary to timely pump out activated sludge.

Summing up, it can be noted that the biological treatment plant has the following main advantages:

• The degree of purification in modern aeration plants exceeds 95%, and the purified water can be sent to water bodies without the installation of additional filtration fields;
• The biological treatment plant is easy to transport. Also, when installing the station, it is not required to carry out large-scale excavation or install it on a concrete base and anchor it;
• The mechanical properties of the casing made of expanded polypropylene make it possible to install the station in any, most "heavy" soil, even with very high level groundwater;
• The durability of the biological treatment plant, its absolute tightness, environmental safety, resistance to corrosion, as well as to the effects of aggressive acids and alkalis, allows the deep biological treatment plant to be operated for at least 50 years.

Where does the choice of an autonomous sewage system begin?

In order to choose a local treatment plant, the consumer first of all needs to answer a few simple questions:

• How many people will live in the house permanently;
• What type of residence will be in your home - seasonal or permanent;
• How many plumbing devices form drains;
• Land area;
• Features of the soil in which the treatment plant will be installed.

Vladimir Pivovarov:

– Knowing that the city's water consumption rate is 200 liters per day per person, each consumer can choose the required volume of a local treatment plant for his home.

An important influence is exerted by the location of the septic tank on the site, soil characteristics and the factor where the treated wastewater will be discharged. Depending on this, a septic tank installation scheme and appropriate additional equipment are selected. So much for classical scheme installation with low level groundwater infiltrators will be required, drainage pipes or a well, in accordance with how you will organize the filtration fields.

Vladimir Pivovarov:

- Gardeners need to remember that planting trees closer than 3 meters from the location of the septic tank is not allowed, especially those trees that have a very powerful root system. And if there are already wells or wells with water on the site, then the installation of a septic tank filtering platform should be carried out at a distance of more than 15 meters from them.

Summing up, we can say that, armed with the necessary knowledge, and most importantly, clearly understanding the capabilities and features of this or that wastewater treatment plant, any developer will be able to choose the most optimal system sewerage and sewage treatment plant.

What are the advantages of a septic tank with a biofilter against the background of familiar designs? How does such a scheme work? Is it difficult to implement it yourself?

Let's figure it out.

What it is

Under the loud name "biofilter" hides only one of the chambers of the multi-chamber septic tank, in which optimal conditions for the reproduction of bacterial colonies.

Which ones?

1. The chamber is filled with large area surface. In industrially produced deep cleaning stations, special plastic products are used in this capacity, outwardly reminiscent of ... ordinary washcloths for dishes.
2. In addition, the vital activity of aerobic (oxygen-absorbing) bacteria requires saturation of wastewater with air. That is why, in the notorious deep biological treatment stations, the biofilter chamber is aerated: air bubbles are pumped to its bottom by a compressor.

Please note: with a lack of oxygen among the cultures that multiply in the biofilter, for obvious reasons, anaerobic bacteria dominate.
Their ability to assimilate organic matter is much more modest than that of aerobic ones; however, they also contribute to wastewater treatment.

How it works

A biofilter for a septic tank is the last stage of wastewater treatment after mechanical separation.

The complete cycle looks like this:

1. The effluent enters the primary clarifier. Its size and shape are selected so that wastewater will spend about three days in it with minimal disturbances. The goal is mechanical separation: heavy sludge settles to the bottom of the sump, light fractions of effluents (feces, fat, etc.) form a dense crust on the surface.
2. The settled waste water gets into the secondary settling tank. The overflow is organized in such a way that it receives wastewater taken below the surface level. Here, in a compartment with an extremely slow laminar (free of disturbances) flow, separation continues: the smallest particles of sludge settle to the bottom.
3. Finally, the moment of truth comes. By this time, water pollution is mainly biological in nature: all heavy suspensions of mineral origin have already been eliminated.
   Waste flows into the biofilter - directly on dinner table to bacterial colonies.
   Those, of course, begin their favorite pastime - they begin to devour organic matter with the release of harmless water, carbon dioxide and a certain amount of volatile hydrocarbons.

The resulting degree of cleaning depends on several factors:

• The size of the bacteria population. Anaerobic cultures, as a rule, need periodic recruits: biologicals are added to the septic tank on a monthly basis.

It is curious: with sufficient aeration of the effluent, aerobic bacteria, in contrast to anaerobic cultures, multiply explosively.
Periodic supplementation of biologics is not required in principle.

• Biofilter filling areas. The more it is, the more wastewater is in contact with the colonies of organically hungry bacteria.
• Water flow rates. Slow motion through the biofilter means maximum cleaning; when the flow is accelerated, bacteria do not have time to process contaminants.

crazy hands

The price of a ready-made deep biological treatment plant for a family of two or three people is at least 60 - 70 thousand rubles. At the same time, a septic tank of sufficient performance, made by hand, will cost 3-5 times cheaper; however, it will provide a much poorer degree of purification.

At a high level of groundwater, soil post-treatment becomes problematic; dumping drains on the relief or using it for irrigation is also not an option: the smell of sewage does not know mercy and stinks on the spot. What to do?

The obvious solution is to screw a biofilter to a one- or two-chamber septic tank.

General principles

1. The most effective scheme is a biofilter with aerobic bacterial cultures and forced aeration. At the minimum volume, it provides the maximum degree.

1. Efficiency comes at a cost. Forget about cheap aquarium compressors: their capacity won't be enough. Our choice is special ones with a capacity of 60-120 liters per minute.

1. It is not enough to simply blow air into the bottom of the biofilter tank. One vertical chain of bubbles will aerate a small fraction of the effluent volume. The simplest aerator is a sewer pipe with a diameter of 40-50 mm plugged at one end with frequent perforations made with a drill with a diameter of 4-5 millimeters.

Tip: with sufficient pump performance, you can use tees to assemble a simple comb that will saturate the entire volume of the biofilter tank with air.

Capacities

We have already found out that a container with an aerated biofilter is only one of the septic tank chambers, the last one on the way of wastewater.

What materials can it be made of?

• The ideal solution is a polyethylene water container. As a rule, in its lower part there is a branch pipe for the relief valve; in our case, it is useful for connecting a compressor. Of course, through check valve: sewage is clearly not in our interests.

Horizontal polyethylene container - a ready-made section for a septic tank.

• In a brick or concrete septic tank, it is possible to fence off a small section in the secondary sump and provide it with two overflows - inlet and outlet.
• Finally, an old steel barrel can act as a container. It will help to keep it from rust simple instruction: the outer and inner surfaces are covered with two layers of bitumen mastic.

Filling

Actually, we have already mentioned the most affordable options.

• Expanded clay is the cheapest filling. A large surface area is provided by its porous structure.

• Somewhat more expensive (but also somewhat more effective) ... yes, plastic washcloths. They fit into the container without sealing, filling its entire volume.

The main purpose of the sewage system in the country is to collect, purify and further drain the wastewater generated when using water for household and hygienic purposes. Also, a suburban sewerage system for a summer residence is able to cope with the processing of feces. At any dacha where people sometimes live, it is necessary to equip a sewer system that will create normal living conditions.

An important component of civilized life is the availability of sewerage and running water. Inhabitants apartment buildings do not think about how the sewer systems function, since all the drains go to a sewer served by city utilities.

Waste water is waste water from sinks, bathtubs, kitchen sinks, and faeces from the toilet. They are removed using an internal pipeline outside the house, and then into the street sewer network.

If there is no centralized drain, then you have to independently lay a sewage system to drain and treat wastewater.

In such cases, you can create:

• all-alloy structure (while thawed and rainwater enter the treatment plant together with household wastewater);
• a separate system (this creates separate drains for melt and rainwater).

The most simple sewerage for a do-it-yourself cottage is created from the following elements:

• yard external network;
• treatment facilities;
• house internal network with plumbing fixtures.

Sewerage scheme in the country

In the event that sewage comes from different ends of the site, then sometimes it is necessary to create more points for the waste disposal. When laying pipes, it is necessary to find out the depth of soil freezing, as well as the level of groundwater. Read also: "".

Choosing a place for the sewer system near the country house

• remoteness from buildings, fences and water supply elements;
• the slope of the site;
• accessibility special equipment to clean the pit.

According to construction and sanitary standards the drainage pit should be removed from residential buildings at a distance of at least 5 meters. It is better to equip the sump at the lowest point of the site in order to facilitate the flow of wastewater into it.

Sewerage system construction

In order to build an effective sewage system with a septic tank, you need to follow the instructions exactly.

In progress:

1. A pit is dug about 3 meters deep, after the completion of the work, the bottom is compacted with a layer of clay.
2. In the case of using concrete, wall formwork is performed. This will require: wooden beam, OSB sheets, plastic pipe cuttings (read also: "").
3. After the formwork, its sheets are fixed in the pit. For this purpose, a wooden beam is used - it is wedged into the formwork sheets in the pit. After the structure is securely fastened and wedged, the pipe cuttings are inserted into the pre-created holes. Pipes are driven into the ground by at least 50 mm so that they do not turn out under the influence of concrete, which can get into the pit.
4. Metal rods are used to reinforce the walls - such a structure will be much stronger. A special hole is required to enter the pipes.
   It is advisable that the septic tank is no more than 15-20 meters from the foundation of the house, but no closer than 5 meters. To calculate the required capacity of the device, you need to multiply the daily rate of waste per person by the number of residents.
5. The bottom of the septic tank is filled with concrete. As for the walls, the concrete or brick used in their construction is plastered. After pouring one part of the pit, the solution is allowed to dry for 2-3 days, then the formwork is rearranged on the other two walls, and concrete is poured again.
6. Depending on the depth of the groundwater and the type of soil, filtering devices are selected. One of the most reliable options is a well made of reinforced concrete rings with a diameter of 1500 millimeters.

1. A mine is being dug, its size should exceed the diameter of the rings by 80 centimeters.
2. A concrete screed is carried out around the perimeter, and the center must always remain free so that wastewater can seep into the ground.
3. 3 rings are placed in the pit with a crane.
4. In the lowest of them, holes with a diameter of 5 centimeters are drilled using a perforator, the distance between them should be about 10 centimeters.
5. The well is filled with filtering material to a height of about 1 meter. Soil, gravel, broken brick and other small materials are used as backfill.
6. The same filling is done between the walls of the well from the outside and the rings. The inlet pipe is installed above the backfill level by 500 millimeters so that it enters the well through the side hole in the reinforced concrete ring.
7. A hatch with two holes is equipped: for the cover and the exhaust riser (respectively 500 and 100 millimeters).

In addition to a septic tank on unstable soil, it is recommended to create a filter well.

Sewer pipe laying

The further from the house the sewer is located, the deeper the entrance of the pipes should be. If this rule is not followed, then the drains will not drain on their own, respectively, you will have to use a pump to pump them out. This will lead to unnecessary costs and hassle.

To lay the pipeline, a trench is dug with a depth of at least 1 meter, otherwise they will have to be insulated. Usually the depth at which pipes are laid depends on the average temperature in winter. For example, in regions with a warm climate, the depth of trenches can be 70 centimeters, and in areas with severe winters, it must be increased to 180 centimeters.

In unstable soil, the bottom of the dug trench is reinforced with a layer of sand about 15 centimeters thick. Then the moat is covered with soil and compacted.

It is better to lay pipes without turns, since it is in these areas that blockages are most often formed. If this is not possible, then a viewing well is set up in this place, which is sealed with concrete, and in some situations with hot bitumen.

Internal sewerage network

Self-creation internal system as follows:

1. Sinks, bathtubs, washbasins and other plumbing fixtures are connected to a riser with a diameter of 50 millimeters. The devices are connected using a pipe of the same diameter with a slope that does not exceed 25 millimeters per linear meter.
2. At the release of any plumbing device, water locks are installed that prevent unpleasant odors from entering the house.
3. The toilet requires a riser with a diameter of 100 millimeters, and pipes are laid at an angle not exceeding 12 millimeters. According to SNiP, a large slope should not be created, since in this case the sewer system will often become clogged.
4. All risers are connected to a prefabricated sewer line that removes waste water from the house. Its diameter should be 100 millimeters.
5. A small window measuring 300x300 millimeters is created in the basement wall or in the foundation of the house in order to lead the sewer network from the building to the street (read also: "").
6. A pipe is placed in the hole made. Be sure to leave a gap of at least 150 millimeters. Otherwise, the pipe may be damaged when the building shrinks.

Autonomous sewerage systems are a complex installation with a characteristic overflow system, filtration and no less complex electronics. Only a competent calculation and observance of the rules and regulations will ensure a long and calm life for the "autonomous system". How to arrange with your own hands an autonomous sewage system for a private house, using "biological weapons" for peaceful purposes?

From the cesspool pit to the biological wastewater treatment plant

Living in a private house is now becoming more comfortable, thanks to the successful and total implementation engineering systems water purification. Autonomous sewerage is the most demanded part of engineering communications.

Starting from the primitive and laborious, do-it-yourself "economy options" - cesspools and septic tanks, modern autonomous sewage systems for a private house are fundamentally different from their predecessors. The organization of sewage systems is based on the principle of deep biological wastewater treatment.

What is the principle of an autonomous sewage system for a home

The work of an autonomous sewage system in a private house is organized according to the wastewater treatment method, which assumes the following stages:

Mechanical (cleaning from coarse fractions)

Biological (purification from organic compounds)

Physicochemical

Waste water disinfection.

At the mechanical stage of cleaning, the effluents pass into a state favorable for the release of suspended solids. The result mechanical cleaning is the removal of up to 70 percent of contaminants and the creation of an even distribution of water in the effluent.

The result of biological wastewater treatment is the degradation of water organic matter using microorganisms (aerobic and anaerobic).

An important stage in wastewater treatment is sludge dewatering or changing chemical composition water. To increase the efficiency of the mechanical process, a flocculant is used in the sewer system.

The final stage of wastewater treatment is based on its disinfection and subsequent salvo discharge.

A simplified diagram of an autonomous sewerage device in a private house for waste disposal consists of the following elements:

Sewerage and fecal waste accumulator

Tanks for cleaning and processing.

But of particular interest are the stations for deep biological treatment of wastewater, which include aeration tanks and digesters.

Aeration tank is an open-type reinforced concrete structure. Waste water is passed through the aeration tank, which contains organic pollutants, air and recirculated sludge in an active state are supplied. In the aeration tank flow type the water circulates continuously. During aeration, the liquid can be in the container for up to several days.

What is deep biological wastewater treatment

Wastewater treatment technology using deep biological treatment plants can be confidently classified as a complex process involving microorganisms. Technologically necessary:

Create conditions conducive to the formation of enzymes

Create conditions for aeration, oxidation and decomposition of substances

In the process of the created life support conditions for the biological purification cycle, the products will be decomposed

To make a technological discharge of cleaning products into a reservoir or onto the relief.

Today there are many models of deep wastewater treatment plants. Recall that ready-made stations from the manufacturer are intended for the disposal of sewage, but in no way for their storage.

The most demanded autonomous sewerage systems are:

Topol - Eco

and this list is updated with new models every year.

Autonomous sewerage, what could be easier! This video will tell you about this.

Deep biological wastewater treatment plants have an impressive cost, but their operational characteristics provide a good degree of wastewater treatment. In addition, the sophisticated technology of sewage treatment allows you to reuse the treated discharged water for irrigation. How to install an autonomous sewage system for your home with your own hands?

Installing an autonomous sewage system yourself

Of course, it is preferable to entrust the installation of an autonomous sewage system to specialists. If you intend to carry out the installation yourself, then first you need to consult with specialists who will help in choosing a place for digging a pit for installation. It will not hurt to draw up a plan and installation scheme.

selection of the installation model for autonomous sewerage

When selecting a plant model, the following initial data are required:

The number of consumers and users of the sewerage system

Location of ground waters and their water pressure level

Geological composition of soil and ground

Working volume of the receiving chamber

Depth of a branch pipe

The prospective place of the salvo discharge of effluents.

Based on the collected data, the selection, purchase and delivery of an autonomous sewage system is carried out.

Useful information

In the model of the treatment plant, the manufacturer indicates the depth of the sewer pipe insertion into the system. This is a height of 1.05 - 1.45 mm from the soil level to the lower edge of the supply pipe.

what to do with your own hands for installation and installation

Installation activities for an autonomous wastewater treatment plant consist of the following stages:

Excavation work

Installation of the station structure into the pit (without concreting)

Insulation of the upper and side parts of the station

Drainage station construction with sand

Laying of supply and discharge pipes (sewer supply pipe Ø110 mm with insulation and Ø110 mm discharge pipe type DGT-PND)

Laying of an electric cable VVG 4x1.5 in a protective tube PND Ø25

Installation of a conical filtration well Ø0.6m. in the upper part, Ø1m. in the lower part, up to 2 m high.

Compressor connections

Installation of a polymer-sand hatch

Backfilling of soil.
